Fix grizzly compat issue in conducor rpc api

When a new parameter was added in revision
0d5fb06b39e8244429be72f05e2066d24572dc2e, it did not properly account
for rpc client side version control added for compatibility during a
rolling upgrade.  This patch adds the ability to send the older message
version if configured to do so.

powervm: make get_host_uptime output consistent with other virt drivers

The powervm driver was filtering out part of the uptime information so
that only system uptime was returned, not the number of users, load,
etc. The hypervisor API sample and the libvirt driver provide the full
uptime output, so this patch makes the powervm driver follow that
convention.

Fixes bug 1196630
